4 | Subject: [PATCH] Force certain "pljava" custom GUCs to be PGC_SUSET. | ||
5 | |||
6 | Future PL/Java versions will close CVE-2016-0766 by making these GUCs | ||
7 | PGC_SUSET. This PostgreSQL change independently mitigates that PL/Java | ||
8 | vulnerability, helping sites that update PostgreSQL more frequently than | ||
9 | PL/Java. Back-patch to 9.1 (all supported versions). | ||
